Planning for Thursday’s Morning and Afternoon breakout groups Questions for report back at end of morning and afternoon sessions: (5-7 minutes each) Name ~1-3 overarching questions, and for each, describe your general approach (data used, statistical or modeling methods, hypotheses tested, future cross-site experiments…) Describe your proposal for the ASM – leader, title, rough sketch Anticipated product(s) Point person, group names, people to invite

Suggested sessions for Inorganic Nutrients 1.Morning: Climate change effects on retention (vs. export) of inorganic nutrients (Giblin) 2.Morning: Climate change effects on inorganic nutrient transformations (Hollibaugh) 3.Morning: Role of nutrients and stoichiometry in controlling primary production and species composition and vice versa? (Seabloom) 4.Morning: Investigation of long-term data using new approaches and models (e.g. Variance structures of nutrient concentrations across space and time) (everyone should do this!!!) volunteer? 5.Morning: Impacts of changing precipitation chemistry over the long-term record (Hamilton) 6.Morning: Cascading impacts of nutrient availability on food webs and vice versa (including the influence of stoichiometry)? (Ruess) 7.Morning: Implications for autotrophs and heterotrophs of long-term changes in microbial nutrient use efficiency (Mack) 8.Afternoon: Coupled biogeochemical processes and stoichiometry - N, P, and organic C dynamics in ecosystems (Kominoski) 9.Afternoon: Greenhouse gas emissions / Ecosystem role in climate-change feedbacks (Silver) 10.Afternoon: Long-term role of human-decision making and its impacts on inorganic nutrients (e.g. Clean water act, populations on sewerage, etc) (Driscoll) 11.Afternoon: Role of disturbance in altering inorganic nutrient dynamics (fire, flood, etc.) (Melack) 12.Afternoon: How do nutrient budgets (and the importance of recycling) vary across the range of LTER sites? (Holbrook) 13.Afternoon: How do nutrient exports/dynamics vary as a function of connectivity (within and across patch types)? (Gooseff)
